Oxygen surface humidifying device

Abstract

An oxygen surface humidifying device comprises a main housing, an intake pipeline and a humidifying liquor storage part; the main housing is internally provided with a surface humidifying part and a humidifying liquor conveying part; the surface humidifying part comprises the water absorbable body of the surface humidifying part and an inner cavity gap taking at least a part of water absorbable body as inner wall; the position of the surface humidifying part in the inner cavity of the main housing is higher than the humidifying liquor storage part; the humidifying liquor conveying part comprises a water absorbable body connected with the humidifying liquor for providing water for the surface humidifying part continuously by means of capillary principle; and the oxygen is humidified by thesmooth wet cavity gap, the oxygen does not enter the liquid water and is not bumped with water vapor vigorously, only the water vapor is brought into the gas stream, thereby reaching the sterilized humidifying effect without noises.

[0002] Oxygen inhalation is the most common clinical treatment method. Humidification is often required before oxygen use. The traditional water-infused humidification method, that is, the bubble-type humidification method, not only easily produces microbial aerosols, but also has obvious noise during the humidification process. The utility model with application number 200820177959.2 The patent discloses a noiseless oxygen humidification device, through which oxygen flows through the surface of the liquid humidifier and water vapor is mixed in to achieve the purpose of sterile and noiseless humidification. In order to achieve a better humidification effect, the distance between the air inlet and the liquid surface When the distance is certain, there will be an optimal oxygen flow corresponding to it, and the flow rate that may be involved in clinical oxygen therapy is between 1L / Min and 12L / Min, with a difference of more than ten times. Recently, when the flow rate is large, the high-speed airflow will still produce aerosols when the high-speed airflow rushes into the humidification fluid, and the possible microorganisms or antibacterial components in the humidification fluid will be brought into the oxygen flow and inhaled into the patient's lungs to cause risks; The surface is far away, and the flow rate is small, most of the oxygen cannot flow through the liquid surface, but directly flows out from the air outlet, which is difficult to fully humidify, and the liquid level gradually decreases with the prolongation of use time, and the humidification effect is difficult to maintain; any inclination of the product during use Both will change the surface area of ​​the humidification fluid and the flow of oxygen in it, thus affecting the constant output of oxygen humidity

[0003] The utility model patent with the application number 200920105528.6 discloses an integrated oxygen absorbing device, which humidifies the oxygen in the way that oxygen flows through the mesh water curtain layer and the sponge honeycomb air-permeable layer in the humidifying device, and sets a humidifying bag and humidifying device. The humidification device is connected to continuously transport the humidification fluid; this solution uses the principle of gravity and siphon to solve the problem of continuous supply of humidification fluid, but the humidification bag must be hung at a position higher than the humidification device, which is inconvenient for clinical operation; a certain hanging height corresponds to a certain A certain humidification fluid supply speed corresponds to an optimal oxygen flow rate, and the clinical oxygen flow rate changes frequently. In order to achieve a better humidification effect, the suspension height of the humidification bag must be constantly adjusted. It is extremely inconvenient to operate; in addition, the filter humidification method will produce obvious gas resistance, especially when the flow rate is large, the pressure in the humidification device will increase, which will interfere with the transportation of the humidification liquid in the humidification bag to the humidification device, and the humidification effect will be improved. unsustainable
